Stephen King's characters have a habit of popping up across multiple stories, sometimes just as a quick reference, sometimes in a larger role. To help keep track of the various denizens of Derry, Castle Rock, and beyond, graphic designer Gillian James has created a handy flowchart.

James doesn't touch the Dark Tower series, which could be the subject of its own flowchart, but she does get into the references to various stories and characters that reach across the Kingverse, exposing many of the "in-jokes" King plants in his works.
